SUMMARY:

Obtaining a mydriasis is essential for ophthalmologic examination and the measurement of the pupil is of great value for studies and follow-up of ocular pathologies. Birds have their ophthalmic particularities, including iris muscle fibers that are striated. These striated fibers are not relaxed with the use of parasypatholytic ophthalmic eye drops commonly used in routine, however, the use of neuromuscular blockers has been a great ally to obtain mydriasis in these species. Currently, traditional pupillary measurement methods are based on the circular form, not fitting with all forms of pupils of animals. There is a need to adapt methods that can be applied in other species. Photographs were taken with the iPhone 12 in direct light (320 luxes) with a distance of 10 cm from the eye of 29 quails(Coturnix coturnix) that was instilled repeated drops of rocuronium bromide (0.2mg) in the right eye until mydriasis and/or arresponsiveness to light was reached. The eyes were photographed with a millimeter ruler above the eye, in parallel, to calibrate the methods by points, circular and diameters. The results showed that the methods for measuring pupilometry are easy to perform and applicability. Satisfactory pupillary dilation, duration of expected blockage, quemosis and akinesia of the upper eyelid were obtained. Intraocular pressure and tear production test without alterations and there was no formation of corneal ulcer. There were no serious side effects. It is concluded that rocuronium bromide produces a mydriasis satisfactorily and safely in quails (Coturnix coturnix) and that the use of pupillometry methods are easily applicable and with satisfactory results in the routine after the adoption of the most appropriate method. Finally, attention should be paid to the anatomical peculiarities of the species to be evaluated in order to avoid result bias.
